In Facebook’s first lobbying disclosure filing with the U.S. Senate since becoming a public company May 18, the social media platform showed no signs of letting up on investing in its political and policy reach to members of Congress, as well as federal agencies, as the Menlo Park, Calif.-based company continues to break its own records.

For the second quarter of 2012, Facebook spent a total of $960,000 on lobbying activities, according to the Senate’s Lobbying Disclosure Act Database. That’s a threefold increase from the same period last year, when the firm spent $320,000.

As a result, Facebook has already spent more on federal lobbying expenditures in 2012 than it did in all of 2011 — $1.35 million – which was, at the time, a record-breaking year. Facebook reported spending $650,000 on federal lobbying efforts in the first quarter of the year.

How does this compare with other tech companies?

The disclosure for Google, generally a lobbying behemoth on Capitol Hill, reveals an investment in lobbying of $3.92 million for the second quarter.

By comparison, Microsoft reported $2,006,000 in expenditures for the second quarter, representing a modest increase over the last quarter. Yahoo — which was in the news this week following the hiring of a new CEO — reported spending $730,000 in the second quarter of 2012, which is more in line with Facebook’s investment.

Facebook is respected for having one of the most seasoned lobbying shops in the nation’s capital, hosting lawmakers at its California campus and in its Washington, D.C., office. The social network also made educational efforts to help members of Congress make the most of the platform and new features, such as the new timeline layout earlier this year.
